Subject: [PATCH V2 00/10] i3c: mipi-i3c-hci-pci: Define Multi-Bus Instances for Intel controllers
Date: Thu, 11 Dec 2025 15:47:59 +0200	[thread overview]
Message-ID: <20251211134809.75872-1-adrian.hunter@intel.com> (raw)

Hi


Changes in V2:
	Add Frank's Rev'd-by for patches 1 - 3
	Drop default driver data
	New patches split from "i3c: mipi-i3c-hci-pci: Add support for
	Multi-Bus Instances"
	Conversion to MFD split into separate patch
	Simplify ID allocation / free
	Correct use of __free()
	Also define instance 0 in driver_data


A MIPI I3C Host Controller with the Multi-Bus Instance capability supports
multiple I3C Buses (up to 15), with one instance of the HCI Register Set
and one instance of I3C Bus Controller Logic for each I3C Bus, in a single
hardware function (e.g. PCIe B/D/F).

Add support for that to mipi-i3c-hci-pci and mipi-i3c-hci and define
Multi-Bus Instances for Intel controllers.

There are also 3 minor tidy-up patches to start with.


Adrian Hunter (10):
      i3c: mipi-i3c-hci: Remove duplicate blank lines
      i3c: mipi-i3c-hci: Stop reading Extended Capabilities if capability ID is 0
      i3c: mipi-i3c-hci: Quieten initialization messages
      i3c: mipi-i3c-hci: Allow for Multi-Bus Instances
      i3c: mipi-i3c-hci-pci: Do not repeatedly check for NULL driver_data
      i3c: mipi-i3c-hci-pci: Enable MSI support
      i3c: mipi-i3c-hci-pci: Use parent MMIO mapping
      i3c: mipi-i3c-hci-pci: Convert to MFD driver
      i3c: mipi-i3c-hci-pci: Add support for Multi-Bus Instances
      i3c: mipi-i3c-hci-pci: Define Multi-Bus Instances for Intel controllers
